The Late Aptian Rajmahal Traps originated through Kerguelen-Plume-related volcanism at the eastern margin of Indian Shield. Clinopyroxene and whole-rock thermobarometry reveals that magmas crystallized P-T conditions ≤~5 kbar/~1100–1200 °C. These pressures correspond to upper crustal depths (≤~19 km). Modeling shows primary were last in equilibrium with mantle ~9 kbar/~1280 corresponding (~33 k...

A causal connection between the location of identified hydrocarbon deposits in upper structural sedimentary cover and gradient amplitudes neotectonic movements is shown. Within framework chosen model, areas, promising for hydrocarbons Riphean-Vendian deposits, taking into account depth penetration deep fluids cover, correspond to certain values motion amplitude gradient. Rock pressure at Moho b...

various sources of geodetic, geological and geophysical information can improve our understanding about the crustal density. in this paper we propose a methodology for determination of crustal density based on terrestrial gravity observations, geopotential models, digital terrain models (dtm), geological maps and cross-sections, deep geophysical profiles, and geoid models. the method can be alg...

Introduction. The topography [1] and gravity [2] of the Moon are dominated by the signatures of impact basins and the mascon gravity anomalies contained within. A method of generating higher resolution crustal thickness models by utilizing the symmetry of the basins is here presented, providing a refined view of the subsurface structure of the basins, with a focus on Orientale. The crustal stru...

New three-dimensional (3-D) Vp and Vp/Vs models are determined for southern California using P and S-P travel times from local earthquakes and controlled sources. These models confirm existing tectonic interpretations and provide new insights into the configuration of geological structures at the Pacific-North America plate boundary. The models extend from the U.S.-Mexico border in the south to...
